Key Facts Illustration (KFI)

You can get a Key Facts Illustration (KFI) for any mortgages you are interested in. This gives you all the information you need to know about the mortgage product, and is standardised so that you can compare mortgages from different lenders on a like-for-like basis. It will detail the monthly payments, interest rates, fees or charges and total amount payable over the term. You can get a KFI for as many mortgages as you like before choosing the one that suits you.

What is a Decision in Principle (DIP)?

Also known as a lending certificate or Agreement in Principle, a Decision in Principle confirms that we would be prepared to lend you the amount you have requested. There is no charge and no obligation to apply for a Nationwide mortgage once you have a Decision in Principle with us.

It is not a guarantee as it is subject to proof of income, as well as any references we request and a valuation of the property (although if you are buying a home, you can still get a Decision in Principle before you’ve found a property)

The Decision in Principle takes into account:

  • whether you can afford the amount you are looking to borrow (based on some information about your income and outgoings)
  • your credit score
  • our lending criteria

Why do I need one?

The Decision in Principle is part of the application process. Also, if you are buying a house, sometimes estate agents or builders will ask for proof that you can get a mortgage for the amount required.

What will I need to get a Decision in Principle (DIP)?

In order for us to give you a Decision in Principle (DIP) you will need details of your:

  • Address history (for the past 3 years)
  • Income and outgoings
  • Current mortgage (if applicable)
  • Bank details - please note: we will not collect any money from you at this stage, this is for credit referencing purposes only

We will let you know immediately whether we are prepared to lend the amount you have requested or whether one of our applications team will need to call you back - at a time you choose - for some additional information.
